CFD Modelling

Services

At FDS Consult we know that our innovative approach works; but we also know that we need to prove it. That’s where computer modelling comes in.

By using the most advanced computer modelling techniques, we can present a clear and substantiated case for a more creative approach to fire design. Our use of Computational Fluid Dynamics Modelling (CFD Modelling) allows us to create a virtual replica of your building and map the spread of fire and smoke to demonstrate how our fire strategy would work in practice. Meanwhile, Evacuation Modelling and Time Equivalence Modelling ensure that we can prove that our evacuation strategies work and our use of Finite Time Analysis can provide the evidence needed to help prevent the over-specification of fire safety measures.

We have the most advanced technology at our fingertips because we’re at the vanguard of what we do and you can rely on our fire engineering consultancy to use these tools to help us secure fire approval for your building. FDS Consult provides CFD modelling that facilitates the building regulations approvals.

Goodmans Fields

This video demonstrates a typical Smoke Clearance car park ventilation system using impulse fans throughout the car park to induce air movement towards the main extract point. In this simulation, the system is extracting 10 Air Changes per Hour of the whole car park for post-fire smoke clearance in accordance with BS 7346-7:2006. It can be seen that the smoke density within the car park increases until 900 seconds into the simulation, at which point the fire is extinguished and the system continues to operate in order to clear the smoke.

Bethnal Green Road Car Park

This video demonstrates a typical Smoke Clearance car park ventilation system using impulse fans throughout the car park to induce air movement towards the main extract point. In this simulation, the system is extracting 10 Air Changes per Hour of the whole car park for post-fire smoke clearance in accordance with BS 7346-7:2006. It can be seen that the car park becomes smoke logged and remains so until 900 seconds into the simulation, at which point the fire is extinguished and the system continues to operate in order to clear the smoke.

Bethnal Green Road Core 3 – left hand corridor

This video demonstrates the function of a typical Fan Assisted Smoke Shaft system, operating both to justify the extended travel distance within the common corridor for Means of Escape and also to demonstrate protection to the staircase during fire fighting activities. The system is a single speed Fan Assisted Smoke Shaft system extracting at a rate of 4.0m3/s through a 0.5m2 shaft. It can be seen from the video that smoke following the occupants of the fire flat as they escape (300-310 seconds) is cleared from the corridor rapidly, negating concerns over the extended travel distance. The model also shows that during fire fighting activities (after 930 seconds into the simulation), the staircase is maintained clear of smoke and the smoke density within the common corridor is limited.
